Workload migration has been an important demand from customers of virtualization platforms to avoid vendor lock-in. Over time it has become even more critical with most IT installations of virtualization platforms having more than one hypervisor in the mix. Realizing this early, Citrix proposed the Open Virtualization Platform (OVF) specification as a packaging format and was instrumental in defining the OVF standard under the auspices of the Distributed Management Task Force (DMTF). The standard has found widespread acceptance across the world. Reflecting this reality, OVF version 1.1 has now reached the status of an international (ISO) standard.

Citrix continues to work with DMTF to refine OVF for many new use cases that are emerging as the industry enters the Cloud era. Citrix has proposed some important updates to the OVF standard in version 2.0, such as encryption and boot order specification,  that improve the range of use cases for OVF. There are various other use cases coming up in the cloud multi-tenancy area and Citrix continues to propose useful extensions to the OVF standard for them. Citrix also continues to work with industry players in developing interoperability tests in order to make workload migration a frictionless experience for IT. Citrix also continues to work with partners, including Microsoft (see), in order to further OVF portability and interoperability.
